Axtorp 160/80 Vertical with Baltic Sea Ground

Axtorp 160/80 VerticalAfter years of using home-brew verticals for Topband it was time for change. In preparation for the contest season 2018-2019 I installed a new vertical for 80 and 160 meter, the commercially produced “Axtorp”. This is a linear loaded vertical from Lannabo Radio, the HF antenna specialist on the Swedish west coast. It stretches 18 meter in physical height, but linear loading makes it electrically longer, almost a 1/2 wave on 80 meter.

144 MHz Added @ SE0X

With the rise of FT8 I was getting curious to explore VHF propagation. Last summer I installed a 144 MHz transverter from HA1YA and a Big Wheel omni directional horizontal antenna. It turned out pretty well, but why stop at dipping your feet. What did I do next to improve performance on 144 MHz? 🙂 Read more ›
